The spinner spreader machine includes a funnel that is automatically or selectively repositionable and associated with the spinner. The funnel is used to vary the product spreading pattern or maintain a consistent product spreading pattern in combination with a varying product delivery rate as the machine traverses a geographic land area. The machine is used to disperse stored products over a geographic land area and advantageously reduces or eliminates product waste as well as surface and ground contamination that results from inefficient spreading of products.
